The invention relates to a portab'lejclamping device for'use in weldingtogetherthe .ends of rails, beamsgirders and;thedike,

and has for its` object to provide a` y simple, V cheap and eficientapparatusyfoniclainping,

the railsin absolute axial align nent jwith during the weldingoperation, To these ends the nvention coinprises two; paralieL raflstraddlng yoke sg-"each yoke .including a recess intei'mediate its endsprovided with; a

.vertical wall to'engage the side of; arail h'ead and a horizontalwali'to, ,engage the rail tread, and means ca rried by each yoke' 'toeXert later-al pressure on the opposite side of the rail head, saidmeanspreferably tak- V ing the form of a'bolt, which is longitudinal lyadjustable in `an obliquehollow boss or socket on the upper part of theyoke, the

bore of which boss orsocket intersects the rail straddling'recess intheyoke, said bolt having a hooked lower end tadapted to be;

drawn into clamping engagementwith the other side of the rail head, andpreferably with 'the lower edge, of -said side, the 'adjustment of thebolt being efiected by a nut on the outer screw-threaded end of theboltFig. 2 is a vertical transverse section through one of the yokes of theclamp.:

Referring to the drawings, 1 indicatesthe body portion of a yok emember, which is provided at each end with the usual ears or sockets 2-2to receive the eustomary ten'- sion bolts provided with nuts 16. Fo'medin the mid section'of the body ofthe yoke is a recess 3, adapted tostraddle the rail head and being somewhat wider than the Width of therail head, said recess being defined by a vertical wall adapted toengage one side'of the rail head, and an npper horizontal wall adaptedto engage the rail tread, the other wall of the recessj normally beingspaced at some distance from the oppositej'side of the rail head. Thebody' of the yoke is reinforced by' a relatvely heavy dsocket member 6'is tobe we1ded,` in the I I, :with the' yokes straddling the respective-railjends and with the correspon'ding'verti-` the recesses 3; in" eachyoke, engaging oneside of each rail head, 'and the horizontal' surfacesof the recesses 'the longitudinal movement v causing the hooked ends 11thereof to `be forced into clamping engagement with the e web onfin i onits top; and' fot-med insaid finis a hollow bossjor Sock et member 6,the bore of which is oylindrical and is inclined atan oblique angleto'the horizontal longitudirial.
